l Thegeneral objectsofthe inventior'i'rareitoV provide anattachment forthe intake*passage of an explosionengine, which is positioned betweenthe carburetor nozzle and the engine cylinder and: by means ofWhiChsuperheated air fand steam from the water jacket'V of the fcylinder Yare kdrawn fintov the charge,lthus insuring slower combustionof the charge, free? dom from knocking and smootheroperation.

fof the engine.

It isun'derstood'in starting an explosion engine, that when the engineis cold, a portion y of thev fuelspray will condense upon the walls of{the intake'manifold willfailto enter thevcylinder and hence it has beenthe customy tojinorease the fuel supply at'thecarburetor nozzle at thattime.V i But when the engine and v haveV become sufficiently heated,'the' further condensation "of the f fuel: will cease, thereby enrichingthe mixture in the explosion cham-- ber beyond the richnes of thekmixture when the engine is cold; f *Y L j 'fl'n' 1 1At`th'is timetherewill not be a suiicient amount of oxygen supplied ,to completethecombustion, leaving` a surplus ofxfuel'uncon sumed which wouldbelconverted intocarbon, in the cylinderunless provision is made to Yysupply the necessaryamount of oxygen.` 30: v

`To accomplish these and other valuable results, theinvention comprisesa device for superheating a supply of moistvapor andin jecting it intothe charge inthe intake'mani- Q fold in such a heatedconditionthat thevapor 35ielements will-be thoroughly mixed with Vfuel gases. v .v Inthis manner the added moisture' will bev sufficient in amount toprovide-for' slower tion ofthe engine. l
